I think you need to realize that a thought is a neuro-chemical activity. With millions of stimuli activitaing these reactions, ever sec, you are essentially multi-tasking. A thought is only a chemical reaction in a certain region of the brain. Whats makes it conscious and unconscious is whether you are focusing in on that particular activity at that particular time. are you trying to imply that people that are above the status quo and can, for instance, do complicated math problems in there head, are doing this in a one step at a time sequential manner?? No...they have the abiltity to multi task there thoughts and computation abilities of their conscious mind. Just do the research and you'll see for yourself.
